Problems solved by technology

[0005] Throughout the whole process, the decoding of the video code stream and the recompression of data in the remote desktop protocol consume a lot of CPU, which greatly affects the number of instances that can run simultaneously on a single server
[0006] The optimization of existing remote desktop presentation protocols for video is basically limited to the protocol itself

Abstract

The invention relates to a video redirection method and system based on a remote desktop presentation protocol. The method comprises the following steps: acquiring a video file of a media player, performing code-stream separation on the video file, sending a decoding request of a video stream to a thin client, wherein the decoding request is sent to the thin client through a constructed virtual decoder, and the virtual decoder is the agency of the local decoder in the thin client; judging whether receiving a decodable feedback of the thin client or not, if the decodable feedback of the thin client is received, sending the video stream and the playing parameter to the thin client through the remote desktop presentation protocol so as to be displayed after the decoding; if the decodable feedback of the thin client is not received, decoding through the media player. Compared with the prior art, the method disclosed by the invention has the advantages as follows: the bandwidth and computation capacity of the server is effectively reduced, and the user experience of watching the high-definition video is improved.

Description

technical field [0001] The invention belongs to the field of computers, and relates to a video redirection method, in particular to a video redirection method and system based on a remote desktop presentation protocol. Background technique [0002] Existing telepresence protocols, such as Redhat's SPICE protocol, optimize some video. By adopting appropriate compression and decompression algorithms at the SPICE protocol layer, bandwidth requirements are reduced and better user experience is achieved. Currently, for video optimization technologies, some companies also use compression at the protocol layer and decompression on the thin client (software decompression / hardware decompression). Although the above method also has a good user experience, the algorithm of first decompressing and then compressing has a huge CPU overhead on the server. [0003] The data flow of the virtualization-based remote desktop presentation protocol during video playback is as follows: figure 1 ...
